Hilo Preseason ID: Pitching Data Dive
January 12, 2024
On Saturday, January 6th, the PBR Hawaii staff hosted it's first event of the calendar year with the Hilo Preseason ID at Wong Stadium in Hilo, Hawaii. This event featured 43 prospects from the 2024 - 2028 classes and allowed our staff an opportunity to get an in-depth look and analysis of the players in attendance.
Earlier this week we began our post-event coverage with our Quick Hits and Statistical Analysis articles. Today, we continue our deep dive into the data collected at the event within this Pitching Data Dive article as we break down the leaders in several different TrackMan metrics on a variety of different pitches.

FASTBALL
MAX VELOCITY (MPH)
Rank | Name | State | School | Class | Pos | Velocity (max) |
1 | Kameron Lee | HI | Waimea | 2024 | RHP | 87.8 mph |
2 | Loren Iwata | HI | Waiakea | 2024 | LHP | 85.6 mph |
3 | Isaac Derego | HI | Honokaa High & Intermediate School | 2026 | RHP | 82.7 mph |
4 | Dayton-Micheal Hanson | HI | Kamehameha Schools Hawaii Campus | 2028 | RHP | 80.0 mph |
5 | Hurley Soong | HI | Waiakea | 2026 | SS | 79.9 mph |
6 | Jerrell Alston | HI | Waiakea | 2026 | OF | 79.9 mph |
7 | Cameron Mateo | HI | Waiakea High School | 2027 | OF | 79.3 mph |
8 | Kaynen Kalama Ulibas | HI | Waiakea High School | 2025 | OF | 78.1 mph |
9 | Kendrick-Allen Stevens | HI | Kamehameha Schools Hawaii Campus | 2027 | C | 76.6 mph |
10 | Zian Wery | HI | Waiakea High School | 2026 | 3B | 75.1 mph |
Max Fastball Velocity: This metric calculates the speed of the pitch as it’s released from the pitcher’s hand.
SPIN RATE (AVG)
Rank | Name | State | School | Class | Pos | Spin Rate (avg) |
1 | Kameron Lee | HI | Waimea | 2024 | RHP | 2302 rpm |
2 | Loren Iwata | HI | Waiakea | 2024 | LHP | 2160 rpm |
3 | Hurley Soong | HI | Waiakea | 2026 | SS | 2155 rpm |
4 | Jerrell Alston | HI | Waiakea | 2026 | OF | 2132 rpm |
5 | Isaac Derego | HI | Honokaa High & Intermediate School | 2026 | RHP | 2117 rpm |
Spin Rate: This metric calculates the rate of spin on the baseball as it leaves the pitcher’s hand, measured in revolutions per minute (rpm). Historical data shows that high-spin fastballs lessen the impact of gravity, allowing for more ‘rise’ (or less fall, in other words) as it carries through the zone. Low-spin fastballs typically indicate the pitch has greater horizontal action, often making it tougher to square up, but generally easier to make contact with, leading to more ground balls, while high-spin fastballs show a correlation with swings and misses.
INDUCED VERTICAL BREAK (AVG.)
Rank | Name | State | School | Class | Pos | IVB (avg) |
1 | Hurley Soong | HI | Waiakea | 2026 | SS | 21.1 in |
2 | Keizen Ono | HI | Waiakea High School | 2027 | 2B | 19.9 in |
3 | Cameron Mateo | HI | Waiakea High School | 2027 | OF | 19.7 in |
4 | Kaden Yoshizumi | HI | Waiakea High School | 2026 | RHP | 19.0 in |
5 | Conor Wallace | HI | Waiakea | 2027 | 1B | 18.1 in |
Induced Vertical Break: Used in short form as "IVB," this metric is most important on fastballs for creating rise and on curveballs for creating depth – it can also have some use when measuring sliders and cutters as well. Sliders tend to be closer to zero inches while cutters are generally between 5 and 15 inches. Usually fastballs and curveballs with large IVB have higher spin efficiencies as well. Sliders generally have very little (closer to zero) IVB and very low spin efficiency. You could also categorize IVB into spin rate as this is part of the “useful movement” you’re looking for. IVB is also a huge part of the vertical approach angle.
HORIZONTAL MOVEMENT (AVG.)
Rank | Name | State | School | Class | Pos | HM (avg) |
1 | Kaynen Kalama Ulibas | HI | Waiakea High School | 2025 | OF | 21.1 |
2 | Jerrell Alston | HI | Waiakea | 2026 | OF | 18.6 |
3 | Isaac Derego | HI | Honokaa High & Intermediate School | 2026 | RHP | 14.4 |
4 | Kameron Lee | HI | Waimea | 2024 | RHP | 14.4 |
5 | Zian Wery | HI | Waiakea High School | 2026 | 3B | 13.8 |
Horizontal Break: Outlined on TrackMan’s own website: “... horizontal movement is measured in inches between where the pitch actually crosses the front of home plate side-wise, and where it would have crossed home plate side-wise if had it traveled in a perfectly straight line from release. A positive number means the break was to the right from the pitcher’s perspective, while a negative number means the break was to the left from the pitcher’s perspective.”
